This is sort of early!Klaine? Not very long before season 3. It was supposed to go one way, then the other, then everything got mixed together and I'm tired as heck so this is what came out.

I'll just say it started from the idea of Kurt giving Blaine a massage and Blaine making those moaning noises, unaware of how sexual they are to Kurt.

(Oh, side note- red tulips' meaning is indeed a declaration of love. Thank you, internet, for this information. Also, if tulips appear several times in my stories- they're just my favorites, so that's why.)

Blaine's Pajama Pants

Kurt opened the door, his hair only half-done, to a hesitantly smiling Blaine. He was early for their movie date, but it's not like he hasn't been early before. He could wait and chat with Kurt while he finished getting ready.

"Hi," he smiled, glancing at Blaine's red bowtie and almost rolling his eyes- Blaine said something about it being his 'lucky bowtie' once.

"Hi." Blaine leaning in to kiss him, short and chaste, before stepping in and presenting Kurt with a small bouquet of red tulips- Kurt knew they meant a declaration of love. "For you," he said with a little bow, as old fashioned as it could get. Kurt giggled, accepting the flowers and pecking Blaine on the lips again.

"Thank you."

When they went up to Kurt's room, depositing the tulips in a vase, Blaine's movements were slower than usual. He blinked heavily, looking like he fought to re-open his eyes each time. He stumbled up the stairs, oblivious to Kurt's worried gaze, and sank onto Kurt's bed as soon as the bedroom's door closed.

"A little tired, are we?" murmured Kurt, laying next to Blaine and tucking a stray curl behind his ear- no gel today; Blaine didn't like gelling a newly-washed hair, and he just got back from his Friday afternoon workout.

"Mm."

Kurt kissed his cheek. "Do you still wanna go, or just have a sleep over instead?" As long as the door was kept open throughout the night, Burt wouldn't mind.

"I… ugh, I'm sorry, darling, I really don't feel like going out tonight. I'm exhausted from workout," he rubbed his eyes with his fists, scrunching his face.

"That's okay. We don't have to go out, Avengers will be there tomorrow," he promised. It's not like Blaine hasn't seen it already, anyways. And a little sleepover never hurt anyone. "I can give you a backrub before we go to bed."

"You would?" Blaine opened blurred eyes at him, smiling.

"Sure, turn around."

"Thank you, angelic boyfriend of mine."

"Sap."

Sitting up on his knees, Kurt helped Blaine out of his light sweater, leaving him in a white undershirt that made his heart beat a little faster. Blaine didn't seem to care, though, burying his face in the mattress and sighing happily when Kurt's hands found the aching spot right under his left scapula.

"Mm, right there," his voice broke into a moan when Kurt's fingers began applying pressure. Kurt could feel his cheeks heat instantly, but kept massaging Blaine's back gently.

Once the big knot dissolved under the heel of Kurt's palm, he moved on lower, gaining more sleepy groans of contentment. He moved his hands back upwards, looking for more knots; when he didn't find any, he curled his hands around Blaine's shoulders and began kneading them rhythmically.

The pleased noises Blaine made had Kurt squirming above him, trying to maintain his pace through a sudden haze of arousal. His squeezes on Blaine's flesh became stronger, and his breathing quickened with each sound of pleasure.

Finally, after what seemed like ages, Blaine murmured something under his breath.

Kurt paused his movements. "What was that, honey?"

"M'falling asleep," he muttered. "Should… change clothes. Borrow pajama pants?" he asked.

Kurt planted a kiss on the back of his neck. "Of course." He rose from the bed, fishing Blaine's pajama pants (he called them that because he never wore them- they were too short for him- and only kept them for Blaine to borrow) out of the bottom drawer.

When he turned around, his breath stuck in his throat- Blaine was already asleep, and apparently previously managed to shimmy out of his pants, and was wearing only his undershirt and a pair of white boxer briefs.

White boxer briefs.

Kurt could see every single detail of Blaine's dick.

He swallowed, quickly looking away and nudging Blaine, who half-woke up only to pull the pajama pants on and fall right back asleep.

"I'm going to tell dad you're staying over," he murmured, even though he knew Blaine couldn't hear him. He just needed to get out of the room, which was way too hot even with Blaine- more or less- covered. Maybe wash his face. Change into his pajamas as well.

Glancing at Blaine one last time before he left the room, he sighed to himself. This boy didn't even realize the affect he had on Kurt.

One day, thought Kurt, Blaine was bound to find out.

He needed a cold shower.
